One of the objects Patented Oct. 27, I1931- UNITED STATES PATENT WILLIAM J'. WADE, 0F FORT MADISQN, IOWA, CAMPBELL, 0F FORT yOFFICE ASSIGNOR 0F ONE-HALF T0 J. MADISON, IOWA HEATING SYSTII FOR AUTOMOBILES Applicationled April 23, 1929. Serial No. 357,584.

This invention relates to heaters for ,automobiles and particularly to those heaters in which the exhaust from the engine is used as a heating agent.

of the invention is to provide a heater of this character in lwhich the exhaust is used for heating water, this water ing used in radiators disposedon the floor of the machine or at any other convenient point, thus doing away with all danhe escape of carb the heating medium within the car.

A .further object is to provide a construction of this character having a heating chamber wherein are disposed water heating coils and provide a pass having a valve so constructed that the exhaust may be discharged directly into the chamber containing the water heating coils or by-passed around said chamber.

Other objects will appeargin the course of the following description.

My invention is illustrated in the accompanving drawings, wherein:`

igure 1 is a longitudinal 4section of an automobile heater constructed in accordance with my invention;

Figure 2 is a horizontal section through the heating drum and through the exhaust pipe and by-pass; s t

Figure 3 is a top plan view of the inlet of the exhaust pipe showing the means whereby the valve is controlled.

ferring to these drawings, a casing having a removable 10a held in place by bolts or 1() designates bottom plate other suitable forward and chamber 10 are the inlet and outlet pipe sections 11-and 12 flanged to fit against the pipe sections 13 and 14 respectively. The pipe section 14 is flanged to enflange on the exhaust pipe 17 leading from the engine.

` It will be understood, ofcourse, 39

wise formed so as to exhaust gases.

Disposed within the chamber 10 is a heating coil 18. One end of this heating coil extends upward through the top d is connected to a T 19. A pipe 20 leads from this T up to the hot water radiator A pipe 22 leads from this T upward and forward to a hot water radiator 23 shown as disposed upon the foot the dash.

I, of course, do not wish to be limited to any particular construction and location of v and 23. I have shown the radiator 21 as being upright and the radiator 23 as being disposed parallel to the foot board, but Il do not wish to be limited to this.

Mounted upon the dash 24 within the cowl or hood is an expansion tank 25 having a filling opening normally closed with a plug 26 having a vent and overflow pipe 27.

prevent any leakage of let 30. The pipe 28 is also connected by a branch 31 tothe coil 23.

e pipe section 13 is formed with a laterally extending branch 32 as shown in Figure 2 and the pipe section 14 is formed with a like branch 33. pipe section 34 is disposed between the ends of these branches, the

e ends of the,

or constituting valve seats. Whenthe valve bears against the shoulders 39, the valve board just in back of 30 this by-pass 35 vailable.

will then divert the exhaust gases into and through the by-pass and out through the inuHler.

When the valve is turned so'as to seat against the shoulders 40, the exhaust gases will be prevented from passing through the Inuiiler and will pass directly through the heating chamber l() and so to the muffler. By adjusting the valve midway of the two seats, it is possible to control the amount of exhaust gases passing into the chamber l() and thereby control the heat. The chamber 10 will preferably be round and preferably made of sheet iron, though not necessarily so. he bottom is removable to permit the removal of soot which may collect on the coils 18.

The rod which leads from the arm 37 will preferably extend to a foot lever or pedal mounted upon a ratchet push rod extend' through the floor of the car so that t valve may be opened to permit the flow o the exhaust through the heating casing l0 against the action of the spring 38.

A heater constructed in accordance with my invention has many advantages over the ordinary heater. By using the flangev joints between the pipe sections, the heater may be readily assembled and also in case of breakage, the parts can be repaired or replaced at very small cost.

The operation of the valve which controls the heating of the coils does not in any way interfere with the Water circulation and the heat is not controlled by stopping the circulation of the Water. Without a by-pass and with .the water circulating system full of Water, the heating coils are liable to burn and warp and cause leakage. The by-pass entirely prevents this, as when it is desired to reduce the heat, the haust gases is diverted entirely to the by-pass so that no heat is passing around the coils.

It will be noted that the coils and coil jacket are vertically disposed. This makes the heating of the Water and the circulation or the water particularly good. The coil 18 may be readily repaired by removing the lower end of the chamber 10. This heater requires no soldering, welding or brazing, and thus may be readily repaired in sm or villages where expert shop Work is una- This heater furthermore may be readily removed from a car in case a car is traded in. The device can be run either in summer or winter without being disconnected as in summer the by-pass causesthe exhaust to pass/around the heater. At the same time the heater'can be used at any moment.

Obviously Ido not Wish to be limited to the particular honstruction shown except as defined in the appended claim as this might be modified in many ways without departing from the spirit of the invention.
